87 octane

  1. Regular or Premium Fuel?

    What type of fuel are you using, Premium/Regular and WHY???

  2. Dyno'd power difference between regular gas (87 octane) and premium gas (92 octane)

    Thought this would make for a good separate thread. The owners manual says you can run regular gas (87 octane) in the 2.3L ecoboost Ranger, so that leads to the natural question if higher octane gas would yield more power. The easy answer is yes, but how much power difference? Tuners have...
